You can use \n , otherwise, You can try with <br/> between two texts.
useEffect(() => {
const unsubscribe = messaging().onMessage(async (remoteMessage) => {
console.log(JSON.stringify(remoteMessage));
Alert.alert(
"A new FCM message arrived!",
JSON.stringify(
remoteMessage.notification.title +"<br/>"+ remoteMessage.notification.body
)
);
});
return unsubscribe;
}, []);

If you know how to handle CSS (I hope you are a front developer), you can line break it with a combination of css' white-space: break-spaces and '\n'.
your.json file
{
text: "I want to show you \nthe text that is line break."
}
your.css file
p {
white-space: break-spaces;
}
Maybe it looks like this.
I want to show you
the text that is line break.

You can use \n and white-space: pre-line;CSS :
const text = "Title\nBody" function App() { return <div className="pre-line">{text}</div> } ReactDOM.render(<App />, document.getElementById('root'))
.pre-line { white-space: pre-line; }
